I am in the early design phase of a very large-scale (global) private cloud deployment. One of my design challenges is centered around multi-site availability. I need to be able to extend a layer-2 domain across multiple sites. Eventually I want to be able to get to the point were I can orchestrate a “follow-the-sun” model where a user or business unit can instantiate a service, application, (whatever), and have the option to enable that application to migrate globally to different data centers as regions come online, and source traffic begins to shift throughout the day. After VMWorld this year, I was very excited with the advancements made in 5.5 particularly with NSX. It seems like it will be a key enabler for my cloud solution. Also, since I am already working with a considerably robust global infrastructure leveraging Cisco gear (Nexus 7k, 5k, UCS, etc), it seems feasible that OTV and LISP can play a key role here as well. I want to document what I am currently...
